Application filed June 6,

The present invention relates to binding posts or fastening devices forthe terminals of electrical conductors and consists in the combinationsand arrangements of elements hereinafter described and particularly setforth in the accompanying claim.

The invention has for its purpose to provide a device of this characterwherein the conductor terminal may be readily ap plied to or removedfrom the clip through the instrument of the terminal piece alone; i. e.,without necessitating the use of the hands or any implement formanipulating the clip as a requisite to applying the terminal piecethereto or for removing the same.

A further purpose resides in providing a terminal clip having theseautomatic features which will securely hold the conductor in firmlygripped or clamped position, readily permitting the insertion andremoval of the conductor and insuring proper electrical contact at alltimes between the conductor and the fastening device.

The invention is further characterized in that the clip is especiallyadapted for that type of work wherein a large number of clips aremounted on a terminal block in close proximity to the end that therespec tive conductors may be applied to position or removed at will,and thereby avoiding the necessity for using both hands, or theimplements usually employed for separating the respective clip membersto receive the terminal pieces as now required.

The invention is shown by way of illustration in the accompanyingdrawings Wherein-' Figure 1 is a perspective view of the preferred formof cli Figure 2 is an e ge-wise elevational view thereof show'in theterminal piece applied;

Figure 3 a side elevational view;

Figure aand edge-wise View of a modified construction of clip; and

Figure 5 a side elevational view of the clip shown in Figure 4.

Referring to the construction in further detail and wherein likereference characters designate corresponding partsin the different viewsshown, 8 designates the base portion a of the clip, and 9 the resilientand parallel side members thereof havingrespectively the angularportions 10 and 11 as shown. The portion 10 is medially cut-away toprovide .a bifurcated member, the parts 12 1923- Serial No. 643,715.

thereof being bent at their terminals to provide the hook elements 13which receive the terminal member'A, as shown in Figures 2 and 3.

The portion .11 is cut-away along both side edges to provide the tongueportion 14 which is in like manner formed with a hook member 15complementary to those formed on the parts 12 and for the same purpose.The portions 12 and 13 cooperate to receive the terminal piece A merelyby forcing said terminal piece lateral-wise against the respectiveangular portions 14. It will be understood that when the terminal piecethus is pressed against said angular portions 14; of the. clip, saidclip member will be wedged apart or separated to receive the terminalpiece which is then fitted into the recess provided by the similarly andoppositely bent portions 13 and 15 as shown.

The'form of clip shown in Figs. 1 and 5 has the side portions 1 Lthereof bentangularly or in a manner similar to the parts 10 and 11 ofthe clip shown in Figs. 1 to 3, and for the same purpose, to wit, toreceive the terminal piece A by forcing the said terminal piecelateralwise against the respective angular portions 14. One of the clipside members .is medially cut away to provide the side portions 15having the function of the members 12, and .in like manner the other.side member is cut away along both of the side edges to provide a tongue16 corresponding with the tongue member 14 of Fig. 1. Both portions 15'and 16 are formed sinuous as shown, to provide the recessl'? to receiveand secure the terminal. member A and the end portions 16of both members15 and 16 are bent outwardly to the end of forming elements having thefunction of angular portions 14; i. e. for wedgirflg apart the resilientclip members by lateralwise pressure of the terminal pieceA forinsertion within the recess 17 Generally stated the construction of theclip shown in Figs. 4 and 5 is the same as that sho-wnin Figs. 1 to 3,differing only that in the former instance provision is made forreceiving the terminal piece A from the top or bottom of the clip, whilein the form shown in Figs. 1 to 3, the terminal piece can' be applied tothe clip from the under side only.

It is to be understood that I do not desire to limit myself to theprecise details of construction and arrangement herein 'set forth, as itis obvious that various modications may be' made therein withoutdeparting from the essential features of the invention.

Having thus described my invention, what I claim as new is A fasteningdevice for electrical conductors comprising a body portion having spacedcomplementary ends bent upwardly and normally overlapping and providedwith diverging surfaces adapted to cause ments for the conductor,substantially as set forth.

In testimony whereofl aflix my signature.
